15 dogs rescued from locked van amid heat wave in Pasadena

PASADENA, Calif. - Fifteen dogs were rescued amid a heat wave gripping Southern California over the weekend. 

According to Pasadena police, the dogs were discovered in a locked, unattended van at Sierra Madre Villa and Electronic Drive. 

Temperatures in the area at that time were around 100 degrees Sunday.

A security guard from a nearby shopping complex heard barking and alerted officers. 

The Pasadena Humane Society is handling the investigation.

As the heat wave lingers, temperatures are predicted to be between 95 and 105 in valley regions and desert areas. The mountains could see temperatures in triple digits as well.

A Heat Advisory will be in place from 10 a.m. Monday through 8 p.m. Tuesday for greater Los Angeles, the Santa Monica Mountains and the San Gabriel and Santa Clarita valleys, the National Weather Service said.

Highs in downtown Los Angeles were expected to exceed 90 degrees through Wednesday.

As a reminder, the Humane Society is reminding all pet owners of the following tips: 

Practice basic summer safety

NEVER LEAVE YOUR PETS IN A PARKED CAR

Not even for a minute! Not even with the car running and air conditioner on. On a warm day, temperatures inside a vehicle can rise rapidly to dangerous levels. On an 85-degree day, for example, the temperature inside a car with the windows opened slightly can reach 102 degrees within 10 minutes. After 30 minutes, the temperature will reach 120 degrees. Your pet may suffer irreversible organ damage or die. Learn how to help a pet left inside a hot car by taking action or calling for help.

Watch the humidity

"High humidity amplifies the negative impact of high temperature on your pet—and in combination, these factors magnify the danger zone," says Dr. Barbara Hodges, DVM, MBA, of the Humane Society Veterinary Medical Association. "When animals pant, moisture from their lungs evaporates and helps reduce their body heat. But high humidity conditions hamper that process and their ability to cool themselves, and their body temperature can skyrocket—rapidly—to dangerous, or even lethal, levels."

Taking a dog's temperature will quickly tell you if there is a serious problem. Dogs' temperatures should not reach over 104 degrees. If your dog's temperature does, follow the instructions below for treating heat stroke.

Limit exercise on hot days

Take care when exercising your pet. Adjust intensity and duration of exercise in accordance with the temperature. On very hot days, limit exercise to early morning or evening hours, and be especially careful with pets with white-colored ears, who are more susceptible to skin cancer, and short-nosed pets, who typically have difficulty breathing. Asphalt gets very hot and can burn your pet's paws, so walk your dog on the grass if possible. Always carry water with you to keep your dog from dehydrating.

Don't rely on a fan

Pets respond differently to heat than humans do. (Dogs, for instance, sweat primarily through their feet.) And fans don't cool off pets as effectively as they do people.

Provide ample shade and water

Any time your pet is outside, make sure they have protection from heat and sun and plenty of fresh, cold water. In heat waves, add ice to water when possible. Tree shade and tarps are ideal because they don't obstruct air flow. A doghouse does not provide relief from heat—in fact, it makes it worse.

Cool your pet inside and out

Whip up a batch of quick and easy DIY pupsicles for dogs. And always provide water, whether your pets are inside or out with you.

Keep your pet from overheating indoors or out with a cooling body wrap, vest or mat. Soak these products in cool water, and they'll stay cool (but usually dry) for up to three days. If your dog doesn't find baths stressful, see if they enjoy a cooling soak.

Watch for signs of heatstroke

Extreme temperatures can cause heatstroke. Some signs of heatstroke are heavy panting, glazed eyes, a rapid heartbeat, difficulty breathing, excessive thirst, lethargy, fever, dizziness, lack of coordination, profuse salivation, vomiting, a deep red or purple tongue, seizure and unconsciousness.

Animals are at particular risk for heat stroke if they are very old, very young, overweight, not conditioned to prolonged exercise, or have heart or respiratory disease. Some breeds of dogs—like boxers, pugs, shih tzus and other dogs and cats with short muzzles—will have a much harder time breathing in extreme heat.

How to treat a pet suffering from heatstroke

Move your pet into the shade or an air-conditioned area. Apply ice packs or cold towels to their head, neck and chest or run cool (not cold) water over them. Let them drink small amounts of cool water or lick ice cubes. Take them directly to a veterinarian.

Prepare for power outages

Before a summer storm takes out the power in your home, create a disaster plan to keep your pets safe from heat stroke and other temperature-related trouble.
